On March 9, the Metro State Board of Trustees approved changing the college's name to Denver State University, after more than a year of study. On Thursday, the board voted to postpone plans to rename the school.

Earlier, officials with the University of Denver have asked a Colorado state senator to pull his bill authorizing the name change, according to the agenda for the Metro State Board of Trustees meeting.

The agenda also said that DU has hired a law firm to work against passage of the name change bill.

In a letter sent to Metro State, lawyers for DU said the university owns the trademark to University of Denver, Denver University and DU.

DU's lawyers said they were concerned that prospective students would be confused by the name Denver State University and the acronym DSU.

"The name Denver State University merely juxtaposes elements of the University of Denver mark and includes the word 'state'," the letter said.

The name change bill had been expected to be introduced at the state Legislature the week of April 25, officials said.
